The slope is 6 because x/y or rise/run and in x equal +1 which is positive 1 and y equal +6 which is positive 6... then you divide y by x which will be 6 divided 1 or 6/1 and that’s how it’s 6 :)
You plug in 3 where you see x and 4 where you see y
3*3+1/4*4^2
9+1/4*16
9+4
13
Remember to follow PEMDAS (order of operations)
parenthesis, exponents, multiply, divide, add, subtract<span />
Y= 3 which would be choice A, because both equations are going to be set equal to eachother, so with that you would put

subtract 5y from 7y, and add the 3 from the left to the 3 on the right. this would leave you with 2y=6 so in this case you would divide both sides by two to get the answer of 3 which is choice A.
Based on the graph, we can see that the x and y values of g(x) will never be negative. They also show an increasing curve that resembles the graph of a square root function. Hence, the parent function of g(x) is y = √x
